Application filed.Y October 30, 1911. Serial No. 657,568.

To allrwtom it may concern Be it known that we, JOHN L. CoUNoILL, JAMES E..THARPE, and THoMAs'M. DALE, citizens of the UnitedStates, residing at Statesville, in the county of Iredell, State` of North Carolina, have invented a new and useful Air-Propelled Car-F an, o f which the following is a specification.

The device forming the subject matter of this application, is adapted to be applied to some portion of a vehicle body, such, for instance, asthe side wall or the top of a railway carriage, the construction being such that when the vehicle is in motion, air will enter a casing to actuate a fan the outside-of the vehicle, which fan is operatively connected with another fan, located within the vehicle, and adapted yto maintain a draft within the vehicle. A further object of the invention` is to provide a device of this type having'a driv-y ing fan of novel and improved form.

A further object of the invention is to Y provide novel means whereby the passengers or the occupants of the vehicle, may, at

will, control theA operation of the structure. Vith the forego-ingV and other objects in view, which will appear as the description proceeds, the invention resides kin the combinationV and arrangement of parts and inv the details of construction hereinafter described and claimed, it being understood that changes in theprecise embodiment of invention herein disclosed can be made within the scope of what is claimed withn out depart-ing from the Spirit of the invention.

In the accompanying. drawingafFigure cutting plane passing through the line A B of Fig. 2; Fig. 2 is a horizontal section, the cutting plane passing through the line G D ofFig. 1; Fig. 3 is a detail of thev driving or actuating fan, enlargedrfrom Fig.-1; Fig. l is a sect-ion on the line C-D of Fig. 3, the cutting plane being located parallel to one ofthe blades;and Fig. 5 is a fragmental section uponthe line E-F of Fi Y lgn the accompanying drawings, the numeral 1 indicates generally, a portion ofk a vehicle body such, for instance, as the side wall of a railway coach. Secured tothe outer face of the body 1 is a `casing`2, having an outstanding iiange 3 whereby the located Vupon n cumscribing groove end `of a screw 27,

casing is immediately assembled with the body 1. The casing 2 is equipped with an intake funnel 4, and with a diagonally disposed outlet funnel 5.

Journaledl for rotation in the casing 2, and located upon the outside of the vehicle body 1 is a driving fan the periphery of which is polygonal, and preferably eightsided, the fan comprising a series of-rim plates 6,having upwardly extended flanges. 7. Spokes 8 unite the rim plates 6 with a tubular hub 9, having a reinforcing plate 10 disposed transversely inits interior.

A shaft 11 extends through the vehicle body 1 and is journaled therein in a manner tobe described hereinafter, one of the threaded Vends of the Shaft 11 passing through the reinforcing plate y6. A' bearing 12 is carried by the outer threaded'end of the shaft 11, and a nut 14, carried by the extremity of the shaft 11, coperates with the bearing 12 in gripping the reinforcing plate 6 of the driving fan, ing fan andthe shaft 11 are heldV for simultaneous rotation. The bearing 12 may be received in a recess 15 formed in the outer so that the drivface of the vehicle bodyfl, the bearing-12 A engaging balls 16 which are heldin the rei cess 15. Upon its inner end,'the shaft 11l carries a bearingv 17, engagingballs 18, located in a recess 19 formed in the inner face of the bodyly of the vehicle. the bearing 17 is the hub 2O of a fan 21, the hub 20 being engaged by a washer 22, held in place by a nut 23 threaded upon the inner end of the shaft 11.

The inner hub 17 is provided with a cir- 211, receiving a strap brake 25, the inner end of whichis connected with a retractile spring 26, secured to one abutment 28, projecting inwardly fromthe vehicle body 1, there being a nut 29, upon the free end of the screw 27, the nut 29 bea ing adapted to engage the abutment 28.

Engaged with i slidably mounted in an Secured to each of the rim plates 6 of the i actuating fan are lugs 30, of polygona'lcrossl section, the faces 31 of the lugs-30 being disposed transversely vof. the driving fan. Mounted upon each of the faces 31 of the lugs 30 are outstanding blades 32, equipped intermediate their ends with outwardly pro.

j'ecting vanes 33. The blades 30 extend diagonally of the faces 31 -upon which they n are mounted, the planes of the blades being disposed out of rectangular relation with respect to the median plane of the actuating or driving fan.

The practical operation of the device is as follows. When the vehicle is in motion, air will enter the intake funnel 4 and impinge against the rim plates 6 of the driving fan in the first instance, the air, as it traverses the rim plates 6, subsequently engaging the faces 31 of the lugs 30, the air ultimately engaging the vanes 33. Owing to the fact that the vanes 33 extend diagonally of the faces 3l upon which they are mounted, the air, in passing between the periphery of the driving fan and the casing 2 will, to some extent, follow a sinuous course. The air, being deflected by the inclined vanes 33, will strike against the outer face of the vehicle body l, and against the casing 2, and be deflected inwardly, toward the median lplane of the wheel, for engagement with the driving fan. The construction of the driving fan is such that this member will have great strength, it being recalled that strength is a necessaryl feature in a device of this type, since the vehicle, moving at a high rate of speed, causes the air to impinge with much force against the driving fan.

It will of course be understood that the driving fan will serve to actuate the fan 2l, which fan 21 will cause a draft within the car or other vehicle. When the occupant of the car desires that the draft be stopped, the wing nut 29 may be rotated, retracting the screw 27, and putting the spring 26 under tension, whereupon the strap brake 25 will engage the bearing 17 and hold the shaft 1l against rotation.

I-Iaving thus described the invention, what is claimed is l. In a device of the class described, a vehicle body; a shaft journaled for rotation in the vehicle body; a fan secured to the outer end of the shaft and having a polygonal periphery; polygonal lugs secured to the faces of the fan; blades extended across the faces of the lugs; a casing applied to the outer face of the vehicle body, the casing inclosing the fan, the casing being pro` vided with an intake member, adapted to receive air when the vehicle is in motion, and to discharge t-he air against the polygonal periphery of the fan, against the faces of the lugs, and against the blades; and a second fan secured to the inner end of the shaft, within the vehicle. l

2. In a device of the class described, a vehicle body; a shaft journaled for rotation in the vehicle body; a fan secured to the outer end of the shaft and provided witha polygonal periphery; polygonal lugs applied to the polygonal faces of the fan, the faces of the lugs extending transversely of the faces of the fan; blades applied to the faces of thev lugs and extended transversely of the fan; a second fan secured to the inner end of the shaft and located within the vehicle body; a casing applied to the outer face of the vehicle body and inclosing the first named fan, the casing having an intake member adapted to receive air when the ven hicle is in motion, and to discharge air against the polygonal periphery of the first mentioned fan, against the faces of the lugs, and against the blades; and means located within the vehicle for holding the shaft against rotation.

In testimony that we claim the foregoing as our own, we have hereto aflixed our sig natures in the presence of two witnesses.
